We investigate the impact on trading characteristics of firms when they announce share repurchases using a relatively new buyback method - Accelerated Share Repurchases (ASRs). We find that trading costs decrease and market quality improves following an ASR announcement. The improvement in...

This paper examines the effect of the reduction in tick size on ex-dividend day stock price behavior taking advantage of a unique data where there are no taxes on dividends and capital gains and the tick size is fixed for all traded securities. These data allow us to differentiate among...

Since European trading now traverses national boundaries, and MTFs are rampant, how have the stock price dynamics changed? Analysing the execution channels NYSE Euronext Paris, Chi-X and BATS in CAC40 stocks, we compare metrics of market efficiency pre/post-MiFID and provide insight into the...

We document both theoretically and empirically a major dependence in both the Information Shares (IS) and Component Shares (CS) approaches to the estimation of the price discovery metrics on the errors arising out of the inversion method of the option value to find the implied stock price, as...

Order imbalances are often taken to be a reflection of trading by informed investors. Yet order imbalances may simply be random shocks, and the price effects associated with the imbalances may reflect the inventory pressures of unbalanced trading rather than information conveyed by informed...

We demonstrate empirically that not all capital flows influence exchange rates equally: Capital flows induced by foreign investors’ stock market transactions have both an economically significant and a permanent impact on exchange rates, whereas capital flows induced by foreign investors’...

The objectives of this project were: • to investigate in detail and to determine quantitatively the effect of magnetic fields on phase transformations, recrystallisation and grain growth of C steels in order to build up a comprehensive basic knowledge that is substantially improved,...

We investigate market liquidity, distribution of private information-based trades, and the cost of capital of publicly traded family firms in Japan. As to the estimation of information asymmetry and illiquidity, we use the private information flow (Adjusted PIN) and the symmetric order inflow...

Trading under limited pre-trade transparency becomes increasingly popular on financial markets. We provide first evidence on traders' use of (completely) hidden orders which might be placed even inside of the (displayed) bid-ask spread. Employing TotalView-ITCH data on order messages at NASDAQ,...

This paper examines a process of order submissions and cancellations in the interbank order driven market of the EUR/PLN currency pair. Our contribution to the existing literature is twofold. We generalize the Asymmetric ACD model (AACD) of Bauwens & Giot (2003) with respect to more than two...
